-Recent changes:
-^^^^^^^^^^^^^^^
-
-20040516:
- The end-user modifiable X11 configuration has been moved
- from /usr/X11R6/lib/X11/

to /etc/X11/.
- Ensure that src and xsrc is up to date, and run
- "make cleandir" in src/x11 before your next build.
-
-20040426:
- Support for the original dynamic sysctl node structure has
- been removed in favor of the newer layout. This affects
- consumers of the create and delete interface, as well as
- the dynamic discovery mechanism. This is believed only to
- be the sysctl(8) binary itself, at this point in time, so
- the only effect of this should be that a sysctl binary
- built from sources dated between 2003/12/04 and 2004/03/24
- will not work on a kernel built from sources dated after
- 2004/04/25. If you need a new sysctl binary but build.sh
- does not work, make sure that your revision of
- src/sys/sys/sysctl.h is 1.112 (or later), and then the
- do the following:
-
- cd /usr/src (or wherever your source tree is)
- make USETOOLS=no includes
- cd lib/libc
- make USETOOLS=no dependall install
- cd ../../sbin/sysctl
- make USETOOLS=no dependall install
-
-20040425:
- The ffs superblock issues listed below under 20040109 and 20030402
- are now automatically addressed by the /etc/rc.d/fixsb script or by
- sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
- invocation mentioned below will continue to work and is now
- automated by those scripts. Note that under certain circumstances,
- affected filesystems upgraded to a -current kernel first before
- upgrading their userland with the fixsb and fsck_ffs fixes may
- encounter a 'freeing free inode' panic when writing to the affected
- filesystem, so it is a good idea to repair the filesystem as soon as
- possible. For more details on the fixsb script, see pr install/25138.
-
-20040418:
- statfs(2) and friends have been replaced with statvfs(2). Before
- installing a newly build userland make sure that you are running
- a newly built kernel with COMPAT_20 set. In addition your libc
- build might not work (undefined SYS_statfs symbol) because make
- clean does not know how to remove files it does not know about
- anymore. Manually remove all generated .S sources and objects
- from the libc build directory.
-
-20040326:
- The method by which athhal-elf.o gets pulled into i386 kernel builds
- has been changed. The file is now stored as a uuencoded file in CVS
- and the generated Makefile will use the new .uue rules from bsd.file.mk
- to build it.
-
- This means you must have the latest bsd.files.mk installed when
- building a kernel without USETOOLS=yes.
-
-20040318:
- A bug in the cgd(4) blowfish code was corrected, without
- provision of backwards compatibility, after several public
- notices over several months. Users of cgd with blowfish cipher
- ONLY must dump their data before updating their kernels, and
- recreate cgd's and restore data using the new kernel. See
- (recent message to current-users, URL when mail-index has updated)
-
-20040313:
- On acorn32, the opms and qms drivers have been withdrawn, and
- the old wsqms driver is now called qms. Kernel config files
- will need updating. See the ones in sys/arch/acorn32/conf
- for examples.
-
-20040125:
- On acorn32, the beep and sysbeep devices are no longer
- needed, and will need to be deleted from kernel configuration
- files.
-
-20040109:
- Compatibility for old ffs superblock layouts has been
- added, and the restrictive fsck checks have been reenabled
- when using those layouts. If you have been using -current
- since 20030402, you may find that fsck again signals fatal
- superblock mismatches. To repair, make sure you have
- an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
- to complete the filesystem upgrade. A message has
- been added to the kernel which should detect this problem.
- See the following discussion for more information:
- http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
-
-20031203:
- New binutils builds may fail due to old dependencies.
- It's necessary to "make cleandir" to ensure that
- the dependencies will be rebuilt correctly.
-
-20031111:
- A newer mkdep is needed. Error noting that is
- cc: Ambiguous abbreviation --
-
-20031008:
- /usr/include/sys/disklabel_mbr.h was removed.
- It's necessary to "make cleandir" to ensure that
- the dependencies will be rebuilt correctly.
-
-20031007:
- A sign exension bug was fixed which set all the high bits
- of our newly expanded ffs fs_flags. This should only
- affect users who installed or upgraded in September of 2003.
- A small utility program was posted to tech-kern which
- should fix this problem, and a warning message was added
- to the kernel which should discover and warn about it. See
- http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
-
-20030906:
- With the addition of siginfo support the old signal trampoline
- code has been deprecated to COMPAT_16. Make sure that your running
- kernel has COMPAT_16 enabled before building userland.
-
-20030801:
- With the new openssl, there is some header and library shuffling.
- rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
- /usr/lib/libdes* before building.
-
-20030703:
- Texinfo was updated to 4.6. To avoid failures when trying to
- build the included texinfo files, do:
-
- cd src/gnu/usr.bin/texinfo
- make MKINFO=no dependall install
-
-20030630:
- Groff was updated to 1.19; it's probably necessary to do
- cd share/mk && make install
- cd src/gnu/usr.bin/groff
- make MKMAN=no dependall install
- (untested).
-
-20030516:
- Due to bugs in the export handling code, invalid export lines
- were accepted before and caused the kernel to panic when
- mountd got restarted because it freed memory that had already
- been freed. This has been fixed and the kernel checks
- export addresses very strictly. If you upgrade your kernel,
- make sure you also upgrade mountd, because if your export
- file contains lines with an old inet4 address syntax (i.e.
- a.b.c or a.b or a), they will get rejected by the new kernel.
-
-20030402:
- The superblock layout for FFS was changed. If you have 1.6
- fsck binaries, they will signal a fatal superblock mismatch
- with the first alternate, because they compare too many
- fields (even ones that aren't useful). If possible, upgrade
- your fsck_ffs binary before using a new kernel.
- None of this signals actual filesystem damage.
-
-20030324:
- sendmail version 8.12.8 was imported. Since sendmail is
- now setgid to the smmsp group, and runs in "collection"
- mode for most common activities, there is a new config
- file called submit.cf that needs to live in /etc/mail.
- The generic submit.cf sample in /usr/share/sendmail/cf
- is named netbsd-msp.cf. Upgrading your regular sendmail
- configuration file is also strongly advised.
-
- See the section named "MESSAGE SUBMISSION PROGRAM" in
- the updated /usr/share/sendmail/README file for more
- information.
-
-20030117:
- Texinfo was updated to 4.3. To avoid failures when trying to
- build the included texinfo files, do:
-
- cd src/gnu/usr.bin/texinfo
- make MKINFO=no dependall install
-
-20021223:
- The METALOG format changed slightly, to remove the leading
- "${DESTDIR}" from path names.
- This only affects people building with UNPRIVED.
- For complete safety, remove the DESTDIR entirely and
- update tools/mtree, before running make build.
-
-20021219:
- CVS repository layout was changed. See the following for details
- if you are using (anonymous) cvs to update your tree.
-
- http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
-
-20021219:
- install(1) had a '-N dbdir' option added, to specify an
- alternate location to look up users & groups (instead
- of the host system passwd(5) and group(5) databases).
-
- The build system was modified to take advantage of
- this option (using ${NETBSDSRCDIR}/etc), so if you
- use USETOOLS==no, you may have to rebuild and
- reinstall usr.bin/xinstall first.
-
-20021130:
- fparseln(3) moved from libutil to libc.
- If building to DESTDIR=/, reinstall the includes
- and rebuild libc:
- make includes
- make do-lib-libc
- If using build.sh, "cd tools/compat && make clean"
- before rebuilding the tools.
-
-20021126:
- The mk.conf(5) variable SYS_INCLUDE has been deprecated,
- including the optional "SYS_INCLUDE=symlinks" support.
- All header files, including are copied into
- /usr/include.
-
-20021121:
- The C run-time support files crtbegin.o and crtend.o
- (and their companions crtbeginS.o and crtendS.o) were
- split up, with new crti.o and crtn.o files resulting.
- This means that libtool needs to be rebuilt once the
- new libraries are installed. The process of rebuilding
- libtool will cause it to automatically notice the new
- required files, but it *must* be rebuilt in order to
- do this.
-
- An out-of-date libtool will result in shared libraries
- which lack _init() and _fini() routines, which means that
- their global contructors/destructors will not be invoked.
-
-20021121:
- A bug related to how ARM ELF objects were tagged has been
- corrected.
-
- NetBSD ARM ELF uses the soft-VFP floating point model by
- default. However, the assembler lacked support for marking
- objects as using the VFP floating point format, and the
- compiler was not properly passing the flag indicating "soft-VFP"
- to the assembler.
-
- Unfortunately, this means that the linker will now consider
- old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
- incompatible with new (properly marked) objects.
-
- The problem will only manifest itself if you attempt to compile
- a new program using the fixed toolchain, and link that program
- against old libraries which do not have the proper "softvfp"
- markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
- WILL CONTINUE TO WORK PROPERLY.
-
- The only work-around for the problem is to recompile all of
- the libraries on the system. The easiest way to do this for
- system libraries is to install a binary snapshot; they are
- generally available on releng.NetBSD.org. Any packages you
- have installed which supply libraries will have to be recompiled
- if you wish to link new programs against those libraries.
-
- If you have questions about this matter, please contact
- port-arm@NetBSD.org.
-
-20021011:
- Systrace has been improved to support privilege elevation.
- Updating the kernel requires the userland part of systrace
- to be rebuilt.
-
-20021010:
- The config(8) grammar was changed to allow options to register
- dependencies on attributes, as well as other options. Users
- must update and reinstall usr.sbin/config before building a new
- kernel.
-
-20021009:
- A new attribute dependency syntax was introduced to config(8),
- which is now used by the SCSI configuration description. Users
- must update and reinstall usr.sbin/config before building a new
- kernel.
-
-20021003:
- Several changes have been made to the autoconfiguration
- framework. Users must update and reinstall usr.sbin/config
- before building a new kernel.
-
-20021001:
- The i386mp branch has been merged. To compile a kernel, users
- will need to add the option 'cpu* at mainbus?' to their configuration
- file. Multiprocessor kernels will need
- ioapic* at mainbus? apid ?
- options MULTIPROCESSOR
- options COM_MPLOCK
-
-20020922:
- MKDYNAMICROOT=yes enabled by default, which means that
- certain shared libraries are installed into /lib, the shared
- linker is installed into /libexec, and all programs in /bin
- and /sbin are dynamically linked.
- If you do not use "make build", you should ensure that
- you have the libraries and shared linker in the new locations,
- with:
- make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
-
-20020917:
- USE_NEW_TOOLCHAIN has been replaced with:
- - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
- there is no working in-tree toolchain (hppa, ns32k, sh5,
- x86_64).
- - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
- root of an external toolchain (e.g. /usr/local/gnu). This
- enables the cross-build framework even for TOOLCHAIN_MISSING
- platforms.
-
-20020906:
- gehenna-devsw has been merged into the trunk. Need to update and
- reinstall usr.sbin/config before building the kernel.
-
-20020822:
- Crunched rescue tools (contents of /bin and /sbin, plus others)
- are now provided in /rescue.
-
- To ensure that these are built statically linked (no matter
- what the setting of LDSTATIC is), use a crunchgen(1) built
- from sources newer than 20020820 (see the next entry).
-
-20020820:
- crunchgen(1) changed to ensure that the generated program
- is statically linked.
-
- Solution: update and reinstall usr.bin/crunch
-
-20020605:
- smmsp user/group has been added for sendmail.
-
- Add the following into /etc/group:
-
- smmsp:*:17:
-
- and the following to /etc/master.passwd (via vipw):
-
- smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
-
-20020515:
- sshd user/group has been added. Need to hand add this in, or sshd
- will not let you log in (with default, or UsePrivlegeSeparation=yes)
+Note that much of the advice in this UPDATING file was written before
+build.sh existed. Nevertheless, the advice here may be useful for
+working around specific problems with build.sh.
- Add the following into /etc/group:
+See also: BUILDING, build.sh, Makefile.
- sshd:*:16:
-
- and the following to /etc/master.passwd (via vipw):
+Recent changes:
+^^^^^^^^^^^^^^^
- sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
+20120507:
+ The database schema for makemandb was changed. You will
+ need to update the database using 'makemandb -f' or wait
+ for the next weekly run to fix it.
+
+20120319:
+ sys/conf/Makefile.kern.inc has been modified to adjust the
+ size of db_symtab automatically. You need to update dbsym in
+ your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
+ you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
+ mk.conf.
+
+20120216:
+ Default for MKCATPAGES changed to NO. Update builds will fail
+ unless DESTDIR is cleaned manually. If you built between 20120207
+ and 20120216, daily and weekly could have created an unreable
+ /var/db/man.db index for apropos. Running makemandb -f or
+ the next run of weekly will fix it.
+
+20111227:
+ If you built between 20111225 and 20111227 you need to remove
+ /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
+ bump has been reverted.
+
+20111125:
+ The "rnd" pseudodevice has been added to sys/conf/std, which
+ means it should no longer be explicitly listed in kernel
+ configuration files. The line "pseudo-device rnd" should be
+ removed from any custom kernel config files users may have.
+
+20111119:
+ A problem with the datastructures used by the rndctl(8)
+ utility (pointers in datastructures in an array, making 32->64
+ bit compatibility very painful) has been fixed in a
+ non-backwards-compatible way. If you replace your kernel,
+ replace your rndctl executable too.
- Also /var/chroot/sshd directory needs to be present (digged as part of
- the build process).
-
-20020426:
- NBUILDJOBS obsoleted in favor of just using -j.
-
-20020426:
- etc/postinstall added, which performs various checks for
- configuration file updates and changes, and can fix most of
- the problems identified.
- This should make it much easier to upgrade a system's
- configuration from earlier systems (as far back as NetBSD 1.5).
-
-20020320:
- needs a new install(1) for its "-a cmd" support.
- Build and install at usr.bin/xinstall before the build.
-
-20020319:
- Raw IPv6 socket now makes strict checking for sa_family and sa_len
- on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
- newer than November 2001 when you upgrade the kernel.
-
-20020311:
- ssh configuration files were moved from /etc to /etc/ssh. Beware
- if you restart your machine from remote. Note that sshd.conf needs
- to be changed (due to the use of "/etc" inside).
-
-20020223:
- Users of the VAX port will need to rebuild and install gas
- so it deal with the now present register prefix used in all
- the VAX assembly files.
-
-20020118:
- ntpd user/group has been added. Need to hand add this in or builds
- will break as mtree aborts early.
-
- Add the following into /etc/group:
-
- ntpd:*:15:
-
- and the following to /etc/master.passwd (via vipw):
-
- ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
-
-20011207:
- If you're attempting to build a snapshot on sparc64 and are getting
- reloc errors from the toolchain groff binary this means your native
- toolchain has some broken C++ bits.
-
- To fix:
-
- Build a new toolchain (i.e. build.sh -t)
- Use the new toolchain to build and install natively (i.e. /usr/lib)
-
- gnu/lib/libgcc
- gnu/lib/libstdc++
-
- After this a snapshot will be able to be built.
-
-20011201:
- In order for a sparc64 build to work you must have a working awk. If
- you've built and installed a system with the new toolchain up to this
- point you do not have a working awk as its ability to do floating
- point is broken.
-
- To build:
-
- remake and install gnu/lib/libgcc
- remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
- against the new libgcc.a)
-
-20011128:
- Kernel config information was changed to use defflag in
- the various "files" files. Bug fixes to config(8) are
- required in order for this to work properly. Make sure
- to build and install in usr.sbin/config before attempting
- to build a new kernel.
-
-20011030:
- libc/locale/wcstod.c now needs new lint(1). Update lint(1)
- before building libc.
-
-20011029:
- The new document BUILDING.mdoc (view with nroff | more, or
- see pre-generated .txt and .html versions) describes the build
- procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
- build process, are intended in the long run to replace this
- manual update log.
-
- Users building a USE_NEW_TOOLCHAIN system should read the
- BUILDING document for caveats. Generally, BUILDING supersedes
- UPDATING for these systems, as tool updating is taken care of
- by the new build system.
-
-20011028:
- src/etc/Makefile now needs install to be able to handle
- symlinks that point to nowhere. A bug in install that
- prevented this was corrected.
-
- Solution: update and reinstall usr.bin/xinstall
- Better Solution: Use the new toolchain and it will just work
- for you.
-
-20011006:
- /etc/mtree/NetBSD.dist has been updated to take advantage of
- absolute path support added to mtree(8). Older mtree(8)s don't
- understand the format.
-
- Solution: update and reinstall usr.sbin/mtree
-
-20011004:
- Crunchgen has been updated to work via reach-over makefiles. Updating
- is suggested before running a snapshot build
-
-20010915:
- The new "ubcperf" code committed by Chuck Silvers removed
- a header file, uvm/uvm_vnode.h. There may be stale .depend
- files that still reference this file.
-
- Solution: "make cleandir && make dependall" in affected
- directories.
-
-20010803:
- grep.info is now built from grep.texi using makeinfo. Since it
- requires makeinfo v4.0, you need to install new texinfo before
- building gnu/usr.bin/grep. To install new texinfo, please follow
- the instruction described in 20010726 entry.
-
-20010803:
- (i386 only): i386 kernel now uses new instructions like
- `fxsave' which old gas doesn't understand. To build the
- kernel successfully, you need to build and install a new toolchain,
- (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
- from your kernel configuration until you rebuild your userland.
- See 20011029 above and BUILDING file in this directory for more information.
- [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
-
-20010731:
- Bootloader update on ELF platforms. DDB in kernels from before
- this will be unable to read symbol tables provided by newer
- bootloaders.
-
-20010726:
- Texinfo was updated to 4.0. To avoid failures when trying to
- build the included texinfo files, do:
-
- cd src/gnu/usr.bin/texinfo
- make MKINFO=no dependall install
-
-20010718:
- Enabled correct .init/.fini processing in crt0. The way this
- was done was to change a -I directive to cc(1), which means
- make(1) will have a stale dependency (it will be checking the
- timestamp on the wrong "dot_init.h").
-
- The symptom you will see is that new programs die with SIGSEGV
- if you have a stale dependency.
-
- Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
- before starting your build.
-
-20010628:
- A construct was added to uvm_page.h that uncovered a bug
- in lint(1). If you get a warning/error about a non-portable
- bitfield, update your lint(1) before proceeding.
-
-20010226:
- Added named user/group to system. Need to hand add this in or builds
- will break as mtree aborts early.
-
- To work around add by hand:
-
- named:*:14:
-
- to /etc/group and add:
-
- named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
-
- to master.passwd (use vipw for instance if doing by hand).
-
- Now a make build should progress.
-
-20010219:
- get/setprogname() added. Any hostprogs that may use this will need
- to be bootstrapped manually until the host system is current.
-
- Known problems: sys/arch/macppc/stand/fixcoff
- usr.sbin/config (adding -DMAKE_BOOTSTRAP to
- CFLAGS and rebuilding should work)
- usr.sbin/mdsetimage - Build a static copy if
- building a snapshot before fully bootstrapped.
-
-20010204:
- prepare the code to compile with stricter gcc flags. in
- particular start eliminating redundant declarations. Yacc
- needs to be installed before make build.
-
-20010114:
- introduce .if commands(target) in make(1). You need to
- bring everything up-to-date first, then without installing
- anything make and install in usr.bin/make, then proceed
- with make build.
-
-20010101:
- bsd.subdir.mk committed 20001230 had a bug which caused
- afterinstall targets to run too soon; update again.
-
-20001230:
- New share/mk files needed to support .WAIT in SUBDIR variables.
- If you get make errors,
- (cd share/mk; make install)
- Also, PRINTOBJDIR has changed and is now used more heavily.
-
-20001019:
- The `ca' device driver has been replaced by `ld'; although the
- major and minor numbers haven't changed, you should update your /dev
+20111001:
+ the prop_*_send_syscall() functions from proplib(3) have been
+ changed and their new version is not backward compatible with the old
+ one. So ensure that all consumers of these functions (currently:
+ quota2 code and its tests) are updated together with the new lib.
+
+20110817:
+ sparc has been changed to use GCC 4.5.3, so any objdir or
+ DESTDIR for them should be deleted before updating.

+20110806:
+ i386 and amd64 have been changed to use GCC 4.5.3, so any
+ objdir or DESTDIR for them should be deleted before updating.
+
+20110805:
+ The update to GCC 4.5.3 requires a non-trivial portion of
+ the tree to be cleaned. Best to delete both objdir and
+ DESTDIR before running this update. So far, only the
+ sparc64, mips and powerpc platforms have changed.
+
+20110803:
+ The layout of external/public-domain/xz has changed. To do an
+ update build you will have to remove the contents of the OBJDIR
+ for external/public-domain/xz/bin by hand as the xz entry there
+ is now a directory.
+
+20110410:
+ The configuration of src/tools/gcc has changed. To do an
+ update build you have to clean both tools/binutils and
+ tools/gcc by hand.
+
+20110328:
+ Building the Xorg binary was moved into a subdirectory to fix
+ ordering issues with "make all". It may be necessary to remove
+ the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
+ if your update build fails, as the "Xorg" entry there is now a
directory.
-20000929:
- The following make directives are obsoleted.
- MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
- By default, RSA is built into libcrypto. IDEA and RC5 will not be
- built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
- additional library libcrypto_{idea,rc5}.
-
+20110121:
+ Assembler files no longer use -traditional-cpp. This can break
+ the build of individual parts of the tree. This is handled
+ correctly by build.sh. Manual builds have to update /usr/share/mk
+ and re-run config(1) for any kernel configurations as needed.
+
+20101217:
+ The tcpdump(8) program was changed to drop privileges and chroot(2)
+ by default. It may be necessary to manually update passwd(5) and
+ group(5) in order to make the program work with existing setups.
+
+20101125:
+ The latest changes to setenv(3) dissallow setting environment
+ variables with names that contain '='. Revision 1.18 of env.c
+ assumed that this was allowed. Installing a new libc with an
+ old copy of /usr/bin/env causes env x=1 printenv | grep x= to
+ break which affects the autoconf tests for dependency finding,
+ so building gcc will end up printing:
+ checking dependency style of gcc... none
+ configure: error: no usable dependency style found
+ Fix it by rebuilding and re-installing env.
+
+20101119:
+ Recent Xorg updates in xsrc/external/mit/ may cause various build
+ or run-time problems. Delete your entire DESTDIR and OBJDIR if you
+ have any build problems with xsrc, or problems with mismatched
+ versions between xorg-server and drivers.
+
+20100604:
+ The update of ATF to 0.9 causes old tests written in shell to fail
+ unless they are rebuilt. If you are building with MKUPDATE=yes,
+ you need to clean the src/external/bsd/atf/tests/ and the src/tests/
+ trees by hand.
+
+20100522:
+ Recent Xorg updates in xsrc/external/mit/ will cause various build
+ problems. Delete your entire DESTDIR and OBJDIR if you have any
+ build problems with xsrc.
+
+20100522:
+ private section of was splitted, and now mklocale(1)
+ include ctype_local.h, so you have to make cleandir in tools/mklocale.
+
+20100520:
+ The location of the xkb compiled descriptions has changed. Please
+ remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
+
+20100222:
+ The shared objects file extension has been changed from .so to
+ .pico, in order to avoid conflicts with shared libraries names
+ libXX.so. All now stale regular .so files can be removed from
+ your object directories.
+
+20100204:
+ The termcap database has been removed from the sources,
+ but has not been marked obsolete so it is not removed
+ from the system when upgrading.
+ As such, you will need to remove them from your object
+ and destination directories.
+
+20091101:
+ After updating, it may be necessary to make the 'cleandir'
+ target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
+ 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
+ src/tools/lex/ and src/usr.bin/lex/.
+
+20091001:
+ On amd64 you must rebuild tools (to get the new binutils)
+ before building a kernel, or the build fails on cpufunc.S.
+
+20091001:
+ An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
+ symlink, failing the build. Delete the link, and the subdir
+ it is in, and retry your build.
+
+20090718:
+ libc build changed so that strchr() provides the extra entry
+ point for index(). Update build of libc.a (and libc_pic.a)
+ may fail because the archive contains the unwanted index.o.
+ (Similarly for strrchr() and rindex().)
+
+20090709:
+ Native Xorg was upgraded again. Builds will probably fail again
+ without a clean objdir, at least for src/external/mit/xorg.
+
+20090616:
+ Native Xorg was upgraded. Builds will need a clean objdir for
+ src/external/mit/xorg. Upgrading a system from sets will not
+ work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
+ subdirectory has been changed into a file, and this needs to
+ be manually "rm -r"'ed before installing xbase.tgz.
+
+20090501:
+ Several new functions were added to string.h/libc, and this
+ can cause autoconf problems during the tool build for people
+ who fail to clean out their tools objects properly. If you
+ note messages about stpcpy, stpncpy or strnlen accompanying a
+ failure during the tool build, clean out all your tools
+ objects and start again.
+
+20090325:
+ The i386 port was switched to i486 default toolchain. This requires
+ cleaning your src/tools directory and $TOOLDIR and rebuilding them.
+
+20090126:
+ The __posix_fadvise50 system call changed assembly stub type. You
+ need to 'rm -f __posix_fadvise50.*' in the libc build directory
+ to avoid using the old assembly stub.
+
+20090202:
+ pkg_install now depends on the pkgdb cache for automatic conflict
+ detection. It is recommented to rebuild the cache with
+ ``pkg_admin rebuild''.
+
+20090110:
+ time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
+ 1. Make sure your kernel has COMPAT_50 in it. Build and install.
+ This is needed even in the MODULAR kernel because there is
+ conditionally compiled code in rtsock.c.
+ 2. make sure build.sh completes and the binaries in a chroot work
+ before installing.
+ 3. If you don't use build.sh and you build directly to root, and
+ your build breaks in the middle, don't despair. Make sure headers
+ are installed properly, and start building libraries first libc
+ and libutil, install them and then continue building all the
+ libraries in src/lib and src/gnu/lib and install them. Once
+ the new libraries are installed, you can restart the build.
+ 4. If you compile packages and you notice link time warnings,
+ rebuild the required packages to update their shared libraries.
+ Any package you rebuild will require rebuilding all the packages
+ that depend on it.
+ 5. Next time you run pwd_mkdb with the new binary, the file
+ will be upgraded and it will not be backwards compatible.
+ 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
+ lastlogx(5)) have been versioned, and there is a heuristic
+ for utmp. You are better off removing the old files after
+ upgrading. The automated clearing of /var/run during
+ boot, and the automated rotating of files in /var/log by
+ newsyslog(8), may mean that you do not have to remove the
+ files manually.
+ 7. The optional accounting file (/var/account/acct, see
+ accton(8)) has not been versioned, and will need to be
+ removed. The automatic rotation of the accounting file by
+ /etc/daily limits the bad consequences of failure to remove
+ the file.
+ 8. Application software that writes time_t to binary files on
+ disk will break or need attention. Most notably: if you are
+ using PostgreSQL < 8.4, you need to dump your databases,
+ rebuild PostgreSQL with the new time_t, then restore.
+
+20081219:
+ config(1) has been updated, and one of the files it creates -
+ swapnetbsd.o - has changed format. You need to rebuild config
+ (done automatically by build.sh) and then you need to rerun
+ config on all kernel configuration files before rebuilding those
+ kernels.
+
+20081205:
+ If you build with MKX11=no, you should remove /etc/rc.d/xdm and
+ /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
+ set and will appear as extra files for MKX11=no update builds.
+
+20081122:
+ On i386, various kernel options(4) in GENERIC including
+ file systems have been disabled and moved into kernel modules.
+ Before trying a new GENERIC kernel, you have to prepare the
+ following files as well as a new GENERIC kernel:
+
+ - build and install kernel modules from src/sys/modules
+
+ - install the latest bootloader, which will load a module
+ for the file system from which the kernel is loaded automatically
+
+ If you have to load your kernel from a file system which is not of
+ the same type as the root file system, you have to load the necessary
+ file system module manually on the boot prompt or in the boot.cfg file.
+
+20080827:
+ If you built and installed a libc from sources between
+ 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
+ which results in false errors reported by lint(1).
+ Since this breaks the libc build itself, manual help is
+ needed -- lint must be disabled temporarily, e.g.:
+ $ (cd lib/libc && make MKLINT=no dependall install)
+
+20080813:
+ MKDEBUG build was broken because the .depend files did not know
+ about .go files. You need to remove all .depend files and rebuild.
+
+20080802:
+ A regression in binary compatibility for pthread_mutex_t has
+ been fixed. Unfortunately, the price is breaking compatibility
+ for -current.
+
+ Threaded programs (using libpthread) and C++ programs (using
+ libstdc++) compiled after 20070907 and before 20080802 need to
+ be recompiled.
+
+ One way to find affected pkgsrc packages:
+
+ $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
+ $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
+
+20080731:
+ WAPBL (metadata journaling support) has been added, but at this
+ time isn't backwards compatible with pre-WAPBL aware kernels
+ and userland (fsck_ffs in particular). Please make sure you
+ don't use a journaled filesystem with an older kernel/userland,
+ especially an uncleanly mounted journaled filesystem. WAPBL
+ also requires the super block to be in the UFS2 format. You
+ can use fsck_ffs -c 4 to update the superblock format.
+
+20080721:
+ Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
+ isn't defined.
+
+20080531:
+ The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
+ from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
+ utility needs to be rebuilt and reinstalled as older binaries
+ won't work correctly. The following sequence of commands:
+
+ $ (cd sys/sys/ && nbmake-$arch includes)
+ $ (cd sbin/drvctl/ && nbmake-$arch clean)
+ $ (cd sbin/drvctl/ && nbmake-$arch all)
+
+ leaves new drvctl utility in sbin/drvctl build directory.
+
+20080503:
+ The variable MKPRIVATELIB was renamed to LIBISPRIVATE.
+
+20080521:
+ For a while, unprivileged UPDATE builds would fail to
+ succeed at the checkflist stage, complaining that
+ ${DESTDIR}/stand// did not exist. A fix for this
+ problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
+ If you already hit this problem, update the .mk file,
+ remove ${DESTDIR}/stand/, and re-run the build.
+
+20080303:
+ Linker warnings are now fatal if $WARNS>0.
+
+20080126:
+ The posix_fadvise system call has been changed from an assembly
+ stub, to a c file that calls an assembly stub. You need to
+ 'rm -f posix_fadvise.* .depend' in the libc build directory to
+ avoid using the old assembly stub.
+
+20071209:
+ The acpiec(4) driver has been split into two attachments. If you
+ get ACPI errors before the attachment, please update your kernel
+ configuration file appropriately or see GENERIC for more details.
+
+20071115:
+ The it(4) driver has been renamed to itesio(4) and the old port
+ argument specified in the kernel configuration file is not valid
+ anymore. The itesio(4) driver now uses the Super I/O address port
+ rather than the EC address port. Please update your kernel
+ configuration file appropriately or see GENERIC for more details.
+
+20071028:
+ The pccons(4) driver has been removed from the NetBSD/shark port.
+ You need to update any custom kernel configuration file you have
+ to remove any references to pccons (which includes removing the
+ now useless XSERVER option) and replace them with the correct
+ entries for the wscons driver. See the GENERIC configuration file
+ for more details.
+
+20070913:
+ A latent bug in dhclient/dhcpd that caused it to be unable to
+ enumerate interfaces was fixed. The bug began to cause
+ problems after 20070911 when the kernel's SIOCGIFCONF
+ implementation was repaired. From 20070529 to 20070911 racoon
+ could not enumerate interfaces. (These are noted because
+ normal kernel/userspace version matching hygiene is not
+ sufficient to avoid this problem.) Ensure that both kernel
+ and userland are from after 20070913.
+
+20070703:
+ nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
+ calls the target-specific strip program, and the logic to pass
+ down STRIP from make has been removed. This requires a
+ re-installation of tools.
+
+20070422:
+ The way OS emulations lookup filenames inside the emulation root
+ has been changed. Rather than modify the pathname (and copy back
+ to userspace) namei() and lookup() directly check the emulation
+ root. One side effect is that absolute symlinks inside the emulated
+ root file system will be relative to that file system - unless they
+ start /../ this is useful when the emulated root is a real install
+ that has such links.
+ This might affect symlinks that have been added to reference outside
+ the emulated root.
+
+20070412:
+ The pckbc driver on sgimips IP32 has been removed. Use macekbc
+ instead. See the GENERIC32_IP3x kernel configuration for an
+ example.
+
+20070319:
+ src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
+ on many platforms due to incorrect flags settings. If you
+ updated and built after about 20070315, do "nbmake-$arch
+ cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
+ rebuild of object files that might have been built
+ incorrectly, and ensure that you have at least
+ src/lib/libc/Makefile 1.130.
+
+20070210:
+ src/sys/sys/{sa.h,savar.h} were removed.
+ find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
+ | xargs egrep -l '/sa.h|/savar.h' | xargs rm
+ will allow dependencies on those files to get get rebuilt
+
+20070209:
+ The threading model was changed when the newlock2 branch
+ was merged to NetBSD-current. If you boot with a new
+ kernel (version 4.99.10), then you also need a new pthread
+ library (/usr/lib/libpthread.so.0.7). If you boot with
+ an old kernel, then you need the old pthread library
+ (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
+ the pthread library in sync, old threaded applications should
+ continue to work with an old or new kernel. Note that named(8)
+ is the only threaded application in the base system.
+
+20061214:
+ Following the move of string_to_flags() and flags_to_string()
+ from the bin/ls/ sources to libutil, users doing UPDATE builds
+ will need to do a "make cleandir" in
+ tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
+ bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
+ usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
+ as the installation images in distrib/
+ in order to excise stale references to the old stat_flags.h header
+ file in the ls sources -- stat_flags.h has been removed.
+
+20061108:
+ The configure script used in the src/tools/gcc compiler has been
+ changed to indicate that our libc has ssp support built-in and
+ does not depend on -lssp and -lssp-nonshared. You'll need to
+ make clean in src/tools/gcc first to rebuild the compiler.
+
+20061009:
+ The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
+ available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
+
+20060814:
+ The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
+ withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
+ kernel configuration for an example. X servers from the last
+ few years should cope.
+
+20060703:
+ MPACPI is no more. We always configure PCI interrupts using ACPI
+ if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
+ to ACPI_SCANPCI. Thanks to work from fvdl.
+
+20060627:
+ socket(2) has changed, and its system call has been versioned.
+ For userlands with the old version of socket(2), make sure that
+ your kernel has 'options COMPAT_30' set, or else 'bad system call'
+ errors will result.
